Study Notes
Colloids in Pharmaceuticals
- Pharmaceutical applications of colloids are mainly related to drug delivery, targeting, and release.
- Lyophilic colloids are characterized by having a strong affinity for the dispersion medium.
- Understanding the behavior of pharmaceutical dispersions is fundamentally dependent on the interaction between the dispersed phase and the dispersion medium.
- Theories in the field of colloidal chemistry, such as the DLVO theory and the Hamaker theory, are helpful for understanding the stability of pharmaceutical dispersions.
- Dispersed systems in pharmaceuticals mainly consist of two phases: the dispersed phase (drug particles or droplets) and the dispersion medium (liquid or gas).
